Presuming that one holder can accommodateВ different sizes of insert (the 11,16 and 22 refer to the length of one side of the triangular inserts which inscribe a circle of 1/4', 3/8' and 1/2' diameter respectively).

ISCAR -В External 55В° partial profile, laydown threading inserts. 4AC Details about 5 Carmex carbide thread mill inserts 30 I 4 ACME MT7. one size for a range of thread pitches with non radiused crests and roots) Good explanation of threading concepts, geometry and terminology. My guess is that a sharp root will decrease the strength of the part, but that is highly unlikely to be an issue at the low working pressure in this application.Д®xplanation of ISCAR threading insert codes. Carmex Spiral Mill-Thread toolholders are specially engineered to maximize thread cutting capabilities. A partial insert will cut a range of pitches but leave flat roots and crests.Д¬armex inserts seem to have the same naming convention as the Iscar, so the 11 IR 11 W example translates to:ДЎ1- insert size 11 (which is 1/4' inscribed circle)ДЄlso, there seems to be some debate as to whether the radius roots and crests are necessary ('only important to amateurs').

Notes - a full profile insert is specific to the pitch and will cut radiused roots and crests. Supplier (at $31USD each!) - (possibly not the best grade of carbide/coating for non-ferrous metal). So, Carmex '11 IR 11 W' or '16 IR 11 W' or '11 IR 11 BSPT' or '16 IR 11 BSPT' or the equivalent Vardex or other competing inserts should do what you want. Only the 'partial profile' inserts leave the crests as-is. If you select the Whitworth or BSP profile Carmex inserts, they will cut the full profile.

For externally threaded parts, the major diameter is nominalВ size plus 1/4', thus 1/4 - 19 is 1/2' diameter (and 19В tpi).ДЇull discussion of how to identify threads and for the 'dash'В naming convention are here and here.Дiscussion of carbide inserts for cutting BSPP threadsД«SPP and BSPT threads are 55 degrees, not 60.ДЄ good visual reference guide to threading standards.ДЄ good discussionВ on Practical Machinist of how to cut BSPT and BSP - which is the same as Whitworth.
